Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a common genetic disease that leads to progressive renal cyst growth and loss of renal function, and is caused by mutations in the genes encoding polycystin-1 (PC1) and polycystin-2 (PC2), respectively. The PC1/PC2 complex localizes to primary cilia and can act as a flow-dependent calcium channel in addition to numerous other signaling functions. The exact functions of the polycystins, their regulation and the purpose of the PC1/PC2 channel are still poorly understood. PC1 is an integral membrane protein with a large extracytoplasmic N-terminal domain and a short, ~200 amino acid C-terminal ...

Law And The Sciences Of The Brain/Mind, 2016 University of Pennsylvania Law School
Law And The Sciences Of The Brain/Mind, Stephen J. Morse
This chapter is a submission to the Oxford Handbook of Law and the Regulation of Technology edited by Roger Brownsword. It considers whether the new sciences of the brain/mind, especially neuroscience and behavioral genetics, are likely to transform the law’s traditional concepts of the person, agency and responsibility. The chapter begins with a brief speculation about why so many people think these sciences will transform the law. After reviewing the law’s concepts, misguided challenges to them, and the achievements of the new sciences, the chapter confronts the claim that these sciences prove that we are really not ...
Identification Of Potential Drug Targets In Cancer Signaling Pathways Using Stochastic Logical Models, 2016 Northwestern Polytechnical University
Identification Of Potential Drug Targets In Cancer Signaling Pathways Using Stochastic Logical Models, Peican Zhu, Hamidreza Montazeri Aliabadi, Hasan Uludag, Jie Han
Pharmacy Faculty Articles and Research
The investigation of vulnerable components in a signaling pathway can contribute to development of drug therapy addressing aberrations in that pathway. Here, an original signaling pathway is derived from the published literature on breast cancer models. New stochastic logical models are then developed to analyze the vulnerability of the components in multiple signalling sub-pathways involved in this signaling cascade. The computational results are consistent with the experimental results, where the selected proteins were silenced using specific siRNAs and the viability of the cells were analyzed 72 hours after silencing. The genes elF4E and NFkB are found to have nearly no ...

Department of Biological Sciences and School of Biomedical Sciences
Professor Glass served as the primary advisor. Ashley Shemery and Alex Yaw served as co-advisors.
Hypothesis: Cocaine irreversibly lengthens circadian period (tau), which could underlie the significant health issues of cocaine addiction. Others have reported that rewarding effects of paternal cocaine use are transgenerational. We hypothesize that the disruptive effects of cocaine on tau may also be transgenerational, causing altered subjective cocaine reward response in offspring (F1).
Methods: Male mice were exposed to cocaine-water (0.5 mg/ml) or water (control) for 6 wks. Immediately following treatment, the mice were mated with cocaine naïve dams. F1 reference for cocaine or sucrose (to test for reward specificity) was analyzed using a dual bottle (water and drug [0.15 mg/ml] or sucrose [2%]) free-choice regimen. Tau was analyzed using activity sensors with computerized data acquisition.
Results and Conclusions: Lengthened tau was evident in sires with forced cocaine compared to controls (24.18+0.17 vs. 24.07+0.02; p0.05). These data reveal that there is no transgenerational transmission of cocaine-lengthened tau in F1 males, but there was an alteration of tau in F1 females. Significantly, paternal cocaine intake significantly altered F1 preference for cocaine, but not sucrose, suggesting specificity to drug reward. Thus, cocaine addiction could involve a transgenerational paternal mode of inheritance.

The purpose of this thesis is to examine familial hypercholesterolemia (FH) and emerging pharmacogenomics therapies that propose to lower serum low density lipid (LDL) levels. The search of various data bases resulted in nine research articles being selected for review. Syntheses of the articles suggest emerging phamacogenomic drug therapy can improve treatment outcomes for individuals with a diagnosis of FH. The Human Genome Project (HGP) has had far reaching applications for genomic technologies and pharmacagenomic interventions, tailored to human conditions associated with select genomic traits. Synthesis of nine research articles demonstrate that little is known on the topic and reveals ...
Comorbidity Between Alzheimer’S Disease And Seizure Episodes, 2016 University of Colorado, Boulder
Comorbidity Between Alzheimer’S Disease And Seizure Episodes, Maryam Amini
Undergraduate Honors Theses
A mouse model of Alzheimer’s disease (AD), which overexpress the human amyloid precursor protein (APP), experience Kainic Acid (KA) induced seizures that are more severe than wild type (WT) mice. The latency and severity of seizures observed in AD mice are similar to those of Synaptophysin knockout (Syp KO) mice. Addition of amyloid plaques (Aβ) to cells in vitro leads to the breakdown of Syp-VAMP2 complex. In the present study, we investigated if the breakdown of Syp-VAMP2 complex is responsible for the observed seizure activity in AD mice. The binding of cholesterol to Syp is necessary for biogenesis ...
Molecular Genetics Of Ms4a6a And Alzheimer's Disease, 2016 University of Kentucky
Molecular Genetics Of Ms4a6a And Alzheimer's Disease, Ryan Harpole
Lewis Honors College Capstone Collection
Increased Alzheimer’s disease (AD) risk has previously been associated with a SNP called rs610932 near the gene MS4A6A. The goal of this experiment was to quantify the expression of two MS4A6A isoforms in the brains of AD and non-AD subjects, particularly as a function of rs610932 genotype. According to an article titled “Alzheimer’s Disease Susceptibility Variants in the MS4A6A Gene are Associated with Altered Levels of MS4A6A Expression in Blood”, MS4A6A has four different isoforms that have been reported to be differentially expressed in the blood of AD subjects compared to non-AD subjects (Petroula et al., 2014). After ...

Robert J. Shprintzen
Velo-cardio-facial syndrome/DiGeorge syndrome, also known as 22q11.2 deletion syndrome (22q11DS) is the most common microdeletion syndrome, with an estimated incidence of 1/2,000 – 1/4,000 live births. Approximately 9–11% of patients with this disorder have an overt cleft palate (CP), but the genetic factors responsible for CP in the 22q11DS subset are unknown. The TBX1 gene, a member of the T-box transcription factor gene family, lies within the 22q11.2 region that is hemizygous in patients with 22q11DS. Inactivation of one allele of Tbx1 in the mouse does not result in CP, but inactivation of ...
Functional Analysis Of Genomic Variation And Impact On Molecular And Higher Order Phenotypes, 2015 University of Tennessee Health Science Center
Functional Analysis Of Genomic Variation And Impact On Molecular And Higher Order Phenotypes, Ashutosh Kumar Pandey
Theses and Dissertations (ETD)
Reverse genetics methods, particularly the production of gene knockouts and knockins, have revolutionized the understanding of gene function. High throughput sequencing now makes it practical to exploit reverse genetics to simultaneously study functions of thousands of normal sequence variants and spontaneous mutations that segregate in intercross and backcross progeny generated by mating completely sequenced parental lines. To evaluate this new reverse genetic method we resequenced the genome of one of the oldest inbred strains of mice—DBA/2J—the father of the large family of BXD recombinant inbred strains. We analyzed ~100X wholegenome sequence data for the DBA/2J strain ...
Role Of Stat3 In Human Nk Cell Functions, 2015 The University of Texas Graduate Schoolf of Biomedical Sciences at Houston
Role Of Stat3 In Human Nk Cell Functions, Prasad V. Phatarpekar
UT GSBS Dissertations and Theses (Open Access)
Natural Killer (NK) cells are cytotoxic lymphocytes, which play a critical role in the immune response against malignant cells and microbial infections. NK cells are equipped with activating receptors, which upon detecting ligands expressed on stressed cells induce cytolytic activity of NK cells. Stimulation of NK cell proliferation and priming of NK cytolytic capability are accomplished by cytokines, which mediate their signals mainly through JAK-STAT signaling pathway. Previously, we found that K562 cells genetically modified to express membrane bound IL-21 (mbIL-21), which predominantly activates STAT3, induce robust expansion and activation of human NK cells. Further investigations revealed role of STAT3 ...

Background: Atrial fibrillation (AF) is the most common dysrhythmia in the U.S. and Europe. Few biomarkers exist to identify individuals at risk for AF. Cardiac microRNAs (miRNAs) have been implicated in susceptibility to AF and are detectable in the circulation. Nevertheless, data are limited on how circulating levels of miRNAs relate to AF or change over time after catheter- ablation.
Methods: In 211 miRhythm participants (112 with paroxysmal or persistent AF; 99 without AF), we quantified plasma expression of 86 miRNAs associated with cardiac remodeling or disease by high-throughput quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR). We used qRT-PCR to ...
Conformational Changes And Translocation Of Tissue-Transglutaminase To The Plasma Membranes: Role In Cancer Cell Migration, 2015 University of South Carolina - Columbia
Conformational Changes And Translocation Of Tissue-Transglutaminase To The Plasma Membranes: Role In Cancer Cell Migration, Ambrish Kumar, Jianjun Hu, Holly Lavoie, Kenneth Walsh, Donald Dipette, Ugra Singh
Background Tissue-transglutaminase (TG2), a dual function G-protein, plays key roles in cell differentiation and migration. In our previous studies we reported the mechanism of TG2-induced cell differentiation. In present study, we explored the mechanism of how TG2 may be involved in cell migration. Methods To study the mechanism of TG2-mediated cell migration, we used neuroblastoma cells (SH-SY5Y) which do not express TG2, neuroblastoma cells expressing exogenous TG2 (SHYTG2), and pancreatic cancer cells which express high levels of endogenous TG2. Resveratrol, a natural compound previously shown to inhibit neuroblastoma and pancreatic cancer in the animal models, was utilized to investigate the ...
Tslp-Induced Mechanisms And Potential Therapies For Crlf2 B-Cell Acute Lymphoblastic Leukemia, 2015 Loma Linda University
Tslp-Induced Mechanisms And Potential Therapies For Crlf2 B-Cell Acute Lymphoblastic Leukemia, Olivia L. Francis
Loma Linda University Electronic Theses, Dissertations & Projects
Childhood CRLF2 B-cell Acute Lymphoblastic Leukemia (CRLF2 B-ALL) is a high-risk form of leukemia that is associated with poor patient survival outcomes. CRLF2 B-ALL is five times more prevalent in Hispanic children than others and is associated with a higher rate of relapse, thus contributing significantly to childhood cancer health disparities. This disease occurs due to alterations of the CRLF2 gene, leading to overexpression of the CRLF2 protein- a component of the receptor signaling complex for the cytokine Thymic Stromal LymphoPoietin (TSLP) on the surface of B-ALL cells. TSLP has been shown to induce proliferation of human and mouse B-cell ...
Genetic Exploration Of Valproate Induced Weight Gain, 2015 Royal College of Surgeons in Ireland
Genetic Exploration Of Valproate Induced Weight Gain, Joseph M. Chukwu
Childhood obesity has both long- and short-term health consequences and is a growing public health problem in Ireland (O’Neill et al, 2007; Finucane et al, 2008; Riddoch et al, 1991). Medications used in the treatment of chronic medical conditions like epilepsy and psychiatric illness might be contributing to this epidemic (Ben-Menachem, 2007, Pickrell, 2013; Martine). Epilepsy affects about 50 million people worldwide with about 40,000 people living with the condition in Ireland (JEC, 2011, Linehan et al, 2010). Sodium valproate (VPA) is an effective anti-epileptic drug, but up to 71% of the patients exposed to the drug ...
Comparison Of Next Generation Sequencing Methodology On The Ion Pgm™ System Performance Versus That On The Sanger Sequencing Method For Hv1 And Hv2 Regions Of Mtdna, 2015 University of North Texas Health Science Center at Fort Worth
Comparison Of Next Generation Sequencing Methodology On The Ion Pgm™ System Performance Versus That On The Sanger Sequencing Method For Hv1 And Hv2 Regions Of Mtdna, Wendy C. Argueta B.S.
Theses and Dissertations
Analysis of mitochondrial DNA in forensic applications has enabled the identification of a missing person through comparison with additional maternal relatives. Most forensic applications are based on sequencing of both hypervariable regions of the mtDNA. Sequencing of these regions has been commonly done using Sanger-type sequencing (STS) methodology, which is expensive, time-consuming and laborious. Next Generation Sequencing (NGS) technology, such as the Ion Torrent PGM™ System platform, overcomes most of these issues. In this study, samples from the Guatemalan population (n=40) were sequenced with both Ion Torrent PGM™ technology and STS methods. A high level of consistency (98%) was ...

Src Homology 2 Domain-Containing 5’-Inositol Phosphatase-2 (Ship2) Is An Effector Of Lymphatic Dysfunction, Germaine D. Agollah
UT GSBS Dissertations and Theses (Open Access)
The lymphatic system is essential for the transport of excess fluid, protein, and foreign materials from interstitial tissues to lymph nodes; for immune surveillance, and to maintain fluid homeostasis. Dysregulated lymphatics can be attributed to pathological conditions including tumor metastasis, inflammation, chronic wounds, obesity, blood vascular disorders, and lymphedema. Of these, lymphedema is the most extreme of lymphatic disorders and is represented by a spectrum of symptoms ranging from mild, subtle presentation to severe, disfiguring, overt presentation. Lymphedema is more manageable in the early stages of disease but severely reduces quality of life with progression. Due to lack of molecular ...
